Skillarum: Conditionally Reproducible Website-to-Agent-Skill Compilation

Skillarum turns selected public website pages into portable SKILL.md documents for agent harnesses such as Codex, Claude Code, and Hermes. Work is separated into five inspectable stages: acquire, prepare, process, parse, and render. The crawler restricts acquisition to configured HTTP(S) origins, honours robots.txt, validates redirects, and records provenance for every page. Source text is delimited as untrusted data for LLM generation; generated code is never executed. The deterministic backend is offline and source-extractive; optional OpenAI and Ollama backends provide provider generation with typed fallback traces. Rendered skills carry provenance manifests, and an evidence-gated research package aggregates run observations into descriptive statistics, figures, and a scholarly manuscript. This release pairs the software source snapshot with the companion manuscript PDF.
